User Acceptance Testing is almost complete.
The test cases are executed.
Most results are passing.
The team is asking for sign-off.
Before you approve the release, stop for a moment.
Do you actually have enough evidence to sign off?
A successful UAT process is more than getting users to click through test cases and mark them as passed.
Here are 10 things I would check before treating UAT as complete.
1. Are the Requirements Covered?
Start with the requirements.
For every important requirement, you should be able to answer:
Where was this requirement tested?
If a requirement has no corresponding test, you may have a coverage gap.
A simple traceability chain looks like:
Requirement
↓
Test Case
↓
Test Result
↓
Evidence
The goal is to know what was tested and why.
2. Were the Right Users Involved?
UAT should involve people who understand the actual business process.
Ask:
- Who performed the testing?
- Which roles were represented?
- Were the relevant workflows tested?
- Were real-world scenarios considered?
A technically successful test doesn't necessarily mean the system works well for every intended user.
3. Do You Have Test Evidence?
A result saying PASS is useful.
Evidence makes it stronger.
Depending on the project, evidence might include:
- screenshots
- documents
- recorded results
- comments
- other supporting information
The important thing is being able to understand what happened during the test.
4. What Happened to the Failed Tests?
Don't only count the passes.
Look at the failures.
For every failed test, ask:
Was it fixed?
Was the fix retested?
Is the issue still open?
Is it blocking the release?
A failed test that has been fixed but never retested is not the same as a successfully verified fix.
5. Are Critical Defects Closed?
Not every defect has the same impact.
A minor UI issue and a failure in a critical business workflow should not necessarily be treated the same way.
Before sign-off, identify the defects that could prevent the organization from successfully using the system.
Then make their status visible.
6. Has Retesting Been Completed?
Fixing a defect is only part of the process.
You also need to verify the fix.
The flow should be:
Failed Test
↓
Defect
↓
Fix
↓
Retest
↓
Verified
Without the retest step, the team may be assuming that the fix worked.
7. Is the Sign-Off Coming From the Right Stakeholder?
UAT results provide evidence.
Sign-off represents acceptance.
Those aren't exactly the same thing.
Make sure the person approving the release is the appropriate stakeholder for the project or business process.
And make the approval traceable.
8. Are Users Ready?
Passing UAT doesn't automatically mean users are prepared for production.
Consider:
- Has training happened?
- Have users received the necessary information?
- Do they understand the new workflow?
- Are additional training sessions needed?
Software can be ready while users are not.
That is still a rollout risk.
9. What Feedback Remains?
Users may have questions, concerns, or issues that don't fit neatly into a test case.
Don't lose that information.
Track important feedback and determine whether it is:
- resolved
- still being investigated
- planned for later
- a blocker
- an accepted risk
The important thing is that it has a visible status.
10. Can You Explain Why You Are Ready?
This might be the most important question.
If someone asks:
“Why are we ready to go live?”
Can your team answer with evidence?
You should be able to point to:
Requirements
+
UAT Results
+
Evidence
+
Defects & Retesting
+
Sign-Off
+
Training
+
Feedback
+
Remaining Risks
That is much stronger than:
“Everyone thinks we're ready.”
UAT Sign-Off Should Be a Decision, Not Just a Checkbox
A UAT sign-off should represent an informed decision based on the state of the software and the people who will use it.
That's why I think it's useful to separate three ideas:
Tested — the software has been validated against defined scenarios.
Accepted — the appropriate stakeholders have approved the result.
Ready — the broader rollout conditions have been considered.
These states are connected, but they aren't identical.
A Simple UAT Sign-Off Checklist
Before signing off, ask:
[ ] Requirements covered
[ ] UAT completed
[ ] Test evidence available
[ ] Failed tests reviewed
[ ] Critical defects resolved
[ ] Fixes retested
[ ] Appropriate stakeholder approval
[ ] User training addressed
[ ] Important feedback reviewed
[ ] Remaining risks understood
If you can't confidently check several of these boxes, the question may not be:
“Can we sign off?”
It may be:
“What is still missing before we can sign off?”
That's an important difference.
How does your team handle UAT sign-off?
Do you use a formal UAT checklist, or is sign-off mainly handled through spreadsheets, meetings, tickets, and emails?
What is the one thing you always check before approving a release?
